Hey Terry! Welcome to Finnigan's! I have 4 peeps here:
Ernie: Fellow Hufflepuff 2 years apart I believe, and also a dancer! He's also a healer in the Janus Thickey ward, so if Richard ever wants to work through some of his PTSD, Ernie'd be willing to help.
Percy: Follows the broom racing circuit both for work and for personal interest, and probably has had some interactions with Bluebottle in the context of Broom Regulation. Also, how old is International Exports and is there somethign specific that they export? Percy has never stopped with his personal interest in International Magical affairs and may know a bit, or even interacted with them if the business was around back when he worked for Crouch Sr.
Gemma: Also follows the circuit, though for different reasons - yes, she loves flying, etc, but some of the people to whom she sells illegal brooms use them on the circuit (brooms with unregulated charms on them to make them faster/etc but could have the potential of 'unfortunate accidents', but people risk it because of the speed and the fact she sells them cheap).
Vikesh: May have looked at the racing circuit, but he's happy in quidditch right now. Vee says that yoga and meditation are good for PTSD (but then he thinks they're good for everything).
